result. This continues until you change the setting for the number of averages
or disable averaging (by setting the number of averages to 0).
In certain situations, the length of time that the
AVERAGING
message is
displayed can be affected by additional factors. When you are measuring
frequency, the current resolution setting, the rate setting, and the quality of
the signal all affect the length of time required to make the measurements and
complete the average computation.
NOTE
If the measurement rate is set to HOLD, and a value larger than 1 is set for
averages, the first set of measurements is not initiated until you press the
Reset/Local
key. When you do, the instrument displays the AVERAGING message
while it takes the first set of measurements. When the first set of measurements
is complete, and the averaging result is displayed, the instrument remains in this
state until you press the
Reset/Local
key to initiate another set of
measurements, change the value for averages back to one, or change the setting
for the measurement rate to SLOW, MED, or HIGH. When the measurement rate
is set to HOLD, the instrument performs a block-average computation instead of
a running-average computation.
